Be it known that I, VVILIJAM J. IWAMI, a subject of the Emperor ofJapan, and resident of the city of New York, borough of Manhattan, inthe county of New York and State of New York, have invented a new andImproved Typewriter Attachment, of which the following is a full, clear,and exact description. I

My invention relates to a typewriter attachment, and aims to provide adevice of this nature by means of which the type may be cleaned.

It is a well appreciated fact that heretofore it has been necessary toclean the faces of the type in a writing machine at frequent intervals,incident to the fact that the type becomes clogged with particles ofribbon, dust, etc. rendering the impression made by the type blurred.This cleaning operation necessitates the use or" a brush or a sharppointed instrument, together with a suitable cleanin fluid-to effect adislodgment of the particles. v

Aside from the time necessary for the accomplishment of the typecleansing, considerable diliiculty has been experienced in that theoperators fingers become soiled, incident to the ink from the ribbonrendering the operation an extremely unpleasant one.

Having these defects in mind, my present invention aims to provide atypewriter attachment by means of which the type may be thoroughly andquickly cleaned without the necessity of soiling the fingers.

A further object of my invention is the construction of a device of thenature specified which may be placed upon the market at a nominalfigure, and further objects of my. invention will appear in the annexedspecification taken in connection with the drawings which latter presentpractical applications of the same, and in which;

Figure 1 is a side view of an attachment embodying myimprovedconstruction and showing the same in one association.

Figure 2 is an enlarged end view thereof.

Figure 3 is a rear view of a slightly different form of attachment thanthat illustrated in the precedin figures.

Figure 4 is an enlarged transverse sectional view taken along the line Mand in the direction of the arrows indicated in Figure 3.

"Figure 5- is a planview of still another adaptation of the attachment,and- Specification of Letters Eabznt. Pctbflll'tfili Acilg, 15,

Figure 6 is a perspective view of the de vice as illustrated inFigur'e'5.

Referringv now more particularly to ures '2 and i, it will be 'seen'thatthe essence of my invention consists in the utilization of a brushelement against which the type to be cleaned is struck. Thus, thereference numeral 10 indicates a base upon which a backmg 11carryingbristles 12 is removably retained, preferably by means of aclamping Figi ring 18, thus rendering the brush portion of the devicerenewable when the same becomes worn. f

As in Figures 1 and 2thebase 10 has secured to it a rearwardlyextendingclip 14 by means of which it may be detachably associatedwiththetype head 15 secured toany type bar-'16, forming a partoi theconventional typewriter action.

1 Thus when an operator desires to effect a cleaning of the type itwill. only be necessary to project one of the type bars by striking oneof the keys 17, subsequent towhich the brush element maybe associatedwith the head 15 by means of the clip 14. By reother keys may now bestruck, and by virtue the cleaning element is associated occupies acentral position, each of the type subse quently projected by pressing"the 'corre spondm'g keys will strike against the bristles 12 thusfreeing the particles of matter lodged within the face "of the type andcleaning the latter. 1 It will be found that, all thus be readilycleansed "withthe' expendiof the type may j ture'of but a min'imumamountof time and 1 it will also be seen that thefingers of the operator willnot be soiled as has heretofore resulted from the accomplishment of thiscleaning operation, it being of course understood that after the same iscompleted, that the base 10 is detached from that type head with whichit has been associated, and the" key of thelatter released. I

In Figures 3 and 4L 1 have shown the cleaning element as forming apermanentpart of a typewriting machine, i. e. one or" the type barsdevoted exclusively as a permanent mounting for the cleaning elementthus rendering the attachment and detachment of the latter unnecessary.

Finally the type illustrated in Figures 5 and 6 it will be seen that thecleaning element aforedescribed is attached to the outer end of one 01"a series of links 18 hingedly interconnected these links When in foldedposition lying as has been indicated in dotted lines in Figure 5 flushagainst the body of the typewriting machine, but being capable ofbeingswung so that the cleaning element Will lie in advance 01"- thetype gap so that obviously any type projected will strike against thesame and be cleansed.

Thus all of the objects set forth in the preamble of this specificationhave been accomplished and it will be appreciated that numerousmodifications of structure might readily be resorted to Without in theleast cleaning element and supporting means for i said cleaning elementsaid supporting means being adapted to be'associated' With a typewriterwhereby said cleaning element may be moved to a point adjacent the typeguide of said typewriter to permit of the type 00,- acting therewith.
